Terror Birds or Phorusrhacids, are an extinct clade of large carnivorous flightless birds that were the largest species of apex predators in South America during the Cenozoic era (Range covers from 62 to 1.8 million years ago). They ranged in height from 1 to 3 m (3 to 10 ft),their closest modern-day relatives are believed to be the 80-centimetre-tall (31 in) seriemas, is known from Texas and Florida in North America. Most phorusrhacids were very fast runners, the feet of the phorusrhacids had four toes, the first of which, known as hallux, was reduced and did not touch the ground, while the others, corresponding to the second, third and fourth toes, were kept on the ground. Phorusrhacid had a highly flexible and developed neck allowing it to carry its heavy head and strike with terrifying speed and power, its developed neck muscles and heavy head could produce enough momentum and power to cause fatal damage to the terror bird's prey, all phorusrhacids are thought to have been carnivorous.
